Stopper rod downward or upward stretch when, lifting cylinder 3-1 piston rod drive support frame 3-2, support frame 3-2 along bracket through slot band
Dynamic second connecting plate 3-3 stretches downward or upward, and under the action of the second sliding rail 3-4, the second connecting plate 3-3 in bracket the
It is slided on two sliding rail 3-4, the displacive transformation of the piston rod of lifting cylinder 3-1 downward or upward is at the second connecting plate 3-3, mobile station
The displacement downward or upward such as 3-6 makes rest part entire lowering or the rising in addition to lifting cylinder 3-1 of lifting body 3.This reality
Example is applied when in use, firstly, wheel hub 9 is placed on mobile station 3-6 by wheel hub pallet 10, and by existing positioning mechanism to wheel
Hub pallet 10 is positioned, and the piston rod rising of lifting cylinder 3-1 makes rest part rise overally in lifting body 3, makes to move
Oil sealing jitter detection apparatus 7 on platform 3-6 and mobile station 3-6 rises on the support plate 4-1 of position-limit mechanism 4, it is therefore an objective to
It falls in mobile station 3-6 on support plate 4-1, achievees the effect that support.Limit gas in the position-limit mechanism 4 of 8 two sides of the bottom of rack
Cylinder 4-3 extends piston rod, and support plate 4-1 is slided on third sliding rail 4-2, in the driving of third sliding rail 4-2 and limiting cylinder 4-3
Under, two pieces of support plate 4-1 are relatively close, stop movement after mobile certain stroke;The mobile station 3-6 of lifting body 3 passes through lifting
The driving of cylinder 3-1 is fallen, and frame reaches its support effect on support plate 4-1.When mobile station 3-6 dropping place, rise cylinder 3-
5 piston rod upwardly extends, and makes to push up on jacking guide pillar 3-7, and jacking guide pillar 3-7 is protruded into wheel hub 9 from bottom to top and inner hub
The inner ring of bearing cooperates, and wheel hub 9 is jacked, and the pushing guide post 2-4 of the press mechanism 2 of top is waited to compress downwards.In jack
After structure 3 completes jacking, decline cylinder 1 extends piston rod, pushes frame 2-3 decline, compresses the lower end surface of pressure head tooling 2-10
Wheel hub 9, then lower air cylinder 2-1 extends piston rod (Fig. 8 is that lower air cylinder 2-1 extends the schematic diagram after piston rod), makes second
Pressure head 2-11 is stretched out out of cavity 2-19 in pressure head tooling 2-10 and is inserted into wheel hub 9 from the top down and the wheel inside wheel hub 9
The inner ring cooperation that hub axle is held, wheel hub 9 is positioned.Jacking guide pillar 3-7 and pushing guide post 2-4 has good positioning after wheel hub 9, press mechanism 2
On motor base 2-7 on motor is installed, the main synchronizing wheel 2-8 rotation of motor driven, main synchronizing wheel 2-8 drives synchronous pulley 2-
5 rotations, synchronous pulley 2-5 rotation will drive sleeve 2-15 rotation, one end of sleeve 2-15 fixed pressure head tooling 2-10, sleeve 2-
Rotation of 15 rotation with dynamic head tooling 2-10, wheel hub 9 hub bearing upper and lower end faces respectively by the second pressure head 2-11
Next in conjunction with the first pressure head 3-8 locating clip, pressure head tooling 2-10 and wheel hub 9 are in stitching state, and therefore, pressure head tooling 2-10 turns
It moves to rotating wheel hub 9, after the rotation of wheel hub 9, remaining detection device: brake disc end face run-out detection device, the inspection of ABS gear ring
The photoelectric sensor 2-9 surveyed on device, oil sealing jitter detection apparatus 7 and the second L shaped plate 2-12 starts to detect wheel hub 9.Work as wheel
After hub 9 measures, the press mechanism 2 of top is lifted, and jacking guide pillar 3-7 is extensive downwards along Z axis under the driving for rising cylinder 3-5
Multiple, two pieces of support plate 4-1 are separate in opposite direction along third sliding rail 4-2 under the driving of limiting cylinder 4-3;Lifting cylinder
The piston rod of 3-1 declines, and drives rest part decline in lifting body 3, restPoses.All cylinders in the present embodiment
Control be all made of the prior art realization.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims
Subject to, replacement, deformation, the improvement that those skilled in the art that any pair of this technology is made is readily apparent that each fall within of the invention
Protection scope.
